IPC: B29C47/02
Filed: 1995-07-17
Abstract: PROBLEM TO BE SOLVED: To provide an antenna with non-directivity and capable of increasing an antenna gain and freely varying length by forming the antenna with a coaxial core shape feed wire in which dielectric coating is applied to a conductor and a coaxial sheath shape antenna element constituted by providing a dielectric layer on the surface of a dielectric partially. SOLUTION: This antenna is constituted of the oaxial core shape feed wire 1, the coaxial sheath shape antenna element 2, a dielectric spacer 3, a connector 4 and a radome 5. The feed wire 1 is formed by applying the dielectric coating 1b to the conductor 1a. While, the length of the dielectric coating 1b is decided by its dielectric constant. In this connection, when the dielectric constant is low, the length is increased, and the antenna gain is increased. On the other hand, when the dielectric constant is high, the length is shortened, and the antenna gain is decreased, however, merit to make an antenna itself compact is obtained. In this regard, the dielectric constant is adjusted corresponding to required characteristic.

Title: Production of waveguide type directional coupler
Inventor: MIHASHI YOSHINOBU
IPC: G02B6/122
Filed: 1987-07-21
Abstract: PURPOSE:To obtain a desired branching ratio by projecting a CO2 laser on the clads positioned between the cores of tapered parts and removing part thereof in such a manner that the branching ratio of a coupler attains a prescribed value. CONSTITUTION:After the laser light emitted form a CO2 laser device 8 is curved downward by a mirror 9, the laser light is condensed by a lens 10 and is projected on the clads 5 positioned between the cores 3 and 4 of the tapered parts 7. Since the CO2 laser light has large absorption in SiO2 glass, the laser light irradiated part of the clads 5 consisting of the SiO2 glass are instantaneously evaporated and removed. The coupling from the cores 3 to the cores 4 is mainly executed in a coupling part 6 at this time, but part of the coupling takes place in the tapered parts 7 as well and, therefore, the coupling constant is changed by partly removing the clads 5 between the cores of the tapered parts. The branching ratio (PC:PT) of the coupler is thus adjusted by changing the amt. of the clads 5 to be removed.

Title: Semiconductor memory device
Inventor: AOYAMA KEIZO
IPC: H01L27/108
Filed: 1985-08-20
Abstract: PURPOSE:To lower possibility of short-circuiting especially between a bit line and a power line for the improvement in the yield rate and reliability by a method wherein a plurality of bit lines, whereto memory cells are connected, and power lines, extending between two pairs of bit lines and in parallel roughly with the bit lines, are provided and the lines hold special relations in terms of interlinear distances. CONSTITUTION:An inequality l1<l2<l3 should be satisfied, where l1 is the distance between two bit lines constituting a bit line pair, l2 the distance between bit line pairs, and l3 the distance between a bit line and a power line supplying a ground-side power level VSS. It follows therefore that the frequency of short-circuiting will be the highest between the two bit lines constituting a pair. The semiconductor memory device, however, will be remedied when all the memory cells belonging to the column are replaced with redundant memory cells. Short-circuiting between bit line pairs will be less than between bit lines and any such short-circuiting will be made up for by replacing all the memory cells belonging to the two columns with redundant memory cells. With the distance l3 being the largest of all, possibilities for short- circuiting between a bit line and a power line will be less than between two pairs of bit lines.
